Embodiments of the present disclosure relate to methods and apparatuses for Reference Signal (RS) transmission. In example embodiments, a method implemented in a network device is provided. According to the method, the network device determines at least one set of CSI-RS resources for transmitting Tracking Reference Signal (TRS) to a terminal device. The network device further determines a first offset between a first slot to transmit a first signal for enabling transmission of the TRS and a second slot to transmit the TRS in the at least one set of CSI-RS resources. The first offset is different from a second offset between a third slot to transmit a second signal for enabling transmission of CSI-RS and a fourth slot to transmit the CSI-RS. The network device transmits a configuration indicating the at least one set of CSI-RS resources and the first offset to the terminal device.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, wherein the CSI-RS for tracking and the CSI-RS are associated with different Quasi-Co-Location (QCL) parameters.
5. The method of claim 1, wherein the CSI-RS for tracking is aperiodic.
6. The method of claim 1, wherein the first signal is transmitted in a Downlink Control Information (DCI) format.
9. The method of claim 1, wherein the first time offset is configured to be a value from a set of values, wherein the set of values consists of values that are larger than 0.
11. The method of claim 10, wherein the CSI-RS for tracking and the CSI-RS are associated with different Quasi-Co-Location (QCL) parameters.
12. The method of claim 10, wherein the CSI-RS for tracking is aperiodic.
13. The method of claim 10, wherein the first signal is received in a Downlink Control Information (DCI) format.
17. The method of claim 10, wherein the first time offset is configured to be a value from a set of values, wherein the set of values consists of values that are larger than 0.
20. The base station of claim 18, wherein the first time offset is configured to be a value from a set of values, wherein the set of values consists of values that are larger than 0.
